Fundamental principles of a clasp assembly

By Dr.Swathi Pai on Saturday, January 17, 2009 with 0 comments

The clasp should be completely passive. The retentive function is activated only when dislodging forces are applied to the RPD.

Each retentive clasp must be opposed by a reciprocal (bracing) clasp arm or another element of the RPD capable of resisting horizontal forces exerted on the tooth by the retentive arm.

Each clasp must be designed to encircle more than 180 (more then ½ the circumference) of the abutment tooth.

The rest should provide vertical support only.
